Sweet cherry tomato and sausage bake

I thought I'd try this different take on sausages (which I served with mashed potato) as the use of balsamic vinegar made it sound like it would be quite flavourful. As I was only cooking for my OH and me I halved the amount of cherry tomatoes I used, which still ended up seeming like way too many. The flavour overall was nice, but not outstanding. This was fairly easy to put together, but I'm not convinced that this is something I'd want to keep making.
